2025-08-20 08:05:28

In the packaging industry, the Folder Gluer Machine is a core piece of equipment that directly affects the efficiency and quality of carton production. However, its complex mechanical structure and automated operation processes mean that operators must undergo systematic training before taking up their posts. Improper operation not only leads to low production efficiency, substandard carton quality (such as uneven gluing or deformed folding), but also poses serious safety risks, such as mechanical pinching or equipment damage. This article will comprehensively analyze the training content that folder gluer machine operators need, covering safety awareness, equipment knowledge, practical skills, fault handling, and daily maintenance, to ensure that operators can use the equipment safely, efficiently, and stably.

1. Safety Operation Training: The Fundamental Guarantee for Production

Safety is the top priority in any industrial production scenario, and training for folder gluer machine operators must start with safety operation. This module accounts for at least 30% of the total training hours, as it directly relates to the personal safety of operators and the stable operation of the equipment.

First, operators need to master the basic safety specifications of the workshop, such as wearing labor protection equipment (safety shoes, gloves, goggles) correctly, and not entering the dangerous area of the equipment during operation. For example, the folder gluer machine’s conveyor belt and folding mechanism are high-risk parts; operators must keep their hands at least 30 cm away from these parts to avoid pinching. In addition, operators should be familiar with the emergency stop button (usually red and located at the front and side of the equipment) and know how to press it quickly in case of an emergency, such as when a cardboard is jammed and the equipment cannot stop automatically.

Second, operators need to learn the safety risks specific to the folder gluer machine. For instance, when the equipment is running at high speed, loose clothing or long hair may be wrapped around the rotating parts, leading to personal injury. Therefore, the training should emphasize that operators must tie their hair up and wear tight-fitting work clothes. Another risk is electrical safety: the folder gluer machine is powered by electricity, and operators must not touch the electrical components with wet hands, nor disassemble the equipment’s electrical cabinet without permission. During the training, instructors can use video cases of safety accidents to enhance operators’ awareness, such as showing cases where operators were injured due to not wearing gloves or not stopping the equipment when clearing jams.

Finally, the safety training should include practical drills. For example, simulate a scenario where the equipment is jammed and the emergency stop button needs to be pressed, or simulate a situation where a operator’s hand is accidentally close to the dangerous area, to let operators practice the correct response methods. Only through repeated drills can operators form muscle memory and ensure that they can handle emergencies calmly in actual work.

2. Equipment Structure and Working Principle Training: Lay the Foundation for Operation

To operate the folder gluer machine proficiently, operators must have a clear understanding of its structure and working principle. This training module helps operators know “what each part does” and “how the equipment works”, so that they can adjust the equipment according to production needs and identify abnormal conditions in time.

First, the training should cover the main components of the folder gluer machine and their functions. A standard folder gluer machine usually includes a feeding unit, a conveying unit, a folding unit, a gluing unit, a pressing unit, and a discharging unit. In the training, instructors can use 3D models or physical disassembly (for old equipment) to show each unit: the feeding unit is responsible for feeding the flat cardboard into the equipment evenly; the conveying unit uses a conveyor belt to transport the cardboard to the folding unit; the folding unit relies on folding plates and rollers to fold the cardboard into the shape of a carton; the gluing unit applies glue to the bonding part of the cardboard (usually using a glue roller or a spray gun); the pressing unit presses the glued cardboard to ensure firm bonding; the discharging unit sends the finished carton to the collection area. Operators need to remember the location and function of each unit, and be able to point out the key parts (such as the glue roller in the gluing unit and the folding plate in the folding unit) when standing next to the equipment.

Second, operators need to learn the working principle of the folder gluer machine. Taking a fully Automatic Folder Gluer Machine as an example, its working process is: the feeding unit automatically separates the stacked cardboard one by one and sends them to the conveying unit; the conveying unit adjusts the speed according to the production requirements (usually 50-200 cartons per minute) and transports the cardboard to the folding unit; the folding unit folds the cardboard along the pre-pressed creases (the creases are usually made by a creasing machine before the cardboard enters the folder gluer machine); at the same time, the gluing unit adjusts the amount of glue according to the thickness of the cardboard (thicker cardboard needs more glue) and applies the glue to the specified position; then the pressing unit uses pressure rollers to press the glued part, making the cardboard bond firmly; finally, the discharging unit sorts the finished cartons and sends them to the next process (such as packaging and warehousing). During the training, instructors can use flowcharts to show this process, and let operators observe the actual operation of the equipment, so that they can connect the theoretical principle with the actual operation.

In addition, the training should also include the difference between different types of folder gluer machines. For example, semi-automatic folder gluer machines require manual feeding and auxiliary pressing, while fully automatic ones can complete the entire process without manual intervention; some folder gluer machines are designed for regular cartons (such as rectangular ones), while others can handle special-shaped cartons (such as triangular or hexagonal ones). Operators need to know the characteristics of the equipment they are using, so that they can avoid misoperation caused by confusing different types of equipment.

3. Practical Operation Training: Master the Core Skills

Practical operation is the key part of the training, as it allows operators to apply the theoretical knowledge to actual work and master the core skills of operating the folder gluer machine. This module usually adopts a “demonstration + practice + guidance” model, and the training time is not less than 40% of the total training hours.

3.1 Pre-operation Preparation

Before starting the folder gluer machine, operators need to complete a series of preparation work, which is an important step to ensure the smooth progress of production and the safety of the equipment. The training content in this part includes:

Check the equipment status: Operators need to check whether the parts of the equipment are intact, such as whether the conveyor belt is loose, whether the glue roller is worn, and whether the folding plate is deformed. If any damaged parts are found, they need to report to the maintenance personnel in time and not start the equipment without permission.

Check the glue supply system: The glue supply system is crucial for the gluing quality of the carton. Operators need to check whether the glue tank has enough glue (the glue level should be between 1/2 and 2/3 of the tank), whether the glue is fresh (expired glue may have poor bonding performance), and whether the glue pipeline is blocked. For example, if the glue pipeline is blocked, the gluing unit will not be able to apply glue normally, leading to unbonded cartons.

Adjust the equipment parameters: According to the size and thickness of the cardboard, operators need to adjust the parameters of the equipment, such as the feeding speed, the folding angle, and the amount of glue. For example, when processing thick cardboard (such as 5mm thick corrugated cardboard), the feeding speed should be reduced (to avoid jamming), the folding angle should be increased (to ensure that the cardboard can be folded in place), and the amount of glue should be increased (to ensure firm bonding). During the training, instructors will demonstrate how to adjust these parameters using the control panel of the equipment (usually a touch screen or button panel), and let operators practice repeatedly until they can adjust the parameters accurately according to the production requirements.

3.2 In-operation Operation

During the operation of the folder gluer machine, operators need to master the skills of monitoring the equipment operation and adjusting in real time. The training content includes:

Monitor the production process: Operators need to observe the operation of the equipment at all times, such as whether the cardboard is conveyed smoothly (no jamming or deviation), whether the folding is in place (no deformation or crease deviation), and whether the gluing is uniform (no missing glue or excessive glue). If any abnormal situation is found, such as the cardboard deviating from the conveyor belt, operators need to stop the equipment in time (using the normal stop button, not the emergency stop button unless it is an emergency) and adjust the position of the guide plate in the conveying unit.

Sample inspection: During production, operators need to take samples of the finished cartons at regular intervals (usually every 10 minutes) to check the quality. The inspection items include: whether the bonding is firm (tear the bonded part by hand, if it is not easy to tear, it is qualified), whether the folding size is accurate (use a ruler to measure the length, width, and height of the carton, and the error should be within ±1mm), and whether the surface of the carton is clean (no glue stains or scratches). If unqualified products are found, operators need to analyze the reasons (such as excessive glue leading to glue stains, or incorrect folding angle leading to size deviation) and adjust the equipment parameters accordingly.

3.3 Post-operation Treatment

After the production task is completed, operators need to do a good job in post-operation treatment to maintain the equipment and ensure the cleanliness of the workshop. The training content includes:

Shut down the equipment correctly: Operators need to follow the correct shutdown procedure: first stop the feeding unit, wait for the remaining cardboard in the equipment to be processed and discharged, then turn off the main power switch of the equipment, and finally turn off the power switch of the glue supply system. Do not turn off the main power directly during the operation of the equipment, as this may cause damage to the equipment’s electrical components.

Clean the equipment: Operators need to clean the glue on the glue roller and glue pipeline (using a special cleaning agent for glue), and wipe the surface of the equipment with a clean cloth to remove dust and debris. For example, if the glue on the glue roller is not cleaned in time, it will solidify and affect the gluing effect of the next production. In addition, operators need to clean the collection area of the finished cartons and ensure that the workshop is tidy.

4. Fault Handling Training: Improve Emergency Response Capabilities

During the operation of the folder gluer machine, faults such as jamming, uneven gluing, and abnormal noise may occur. If operators cannot handle these faults in time, it will lead to prolonged production downtime and increased production costs. Therefore, fault handling training is an important part of the operator training.

4.1 Common Faults and Their Causes

First, the training should introduce the common faults of the folder gluer machine and their possible causes. For example:

Cardboard jamming: The causes may include uneven feeding (the cardboard is stacked too high), worn conveyor belt (the friction is insufficient to transport the cardboard), or incorrect adjustment of the folding plate (the cardboard is blocked when passing through the folding unit).

Uneven gluing: The causes may include insufficient glue in the glue tank, blocked glue pipeline, worn glue roller (the glue cannot be evenly applied), or incorrect adjustment of the glue amount (too much or too little glue).

Abnormal noise: The causes may include loose parts (such as screws of the folding unit), lack of lubrication in the rotating parts (such as bearings of the conveyor belt), or damaged gears (the meshing is not smooth).

Instructors can use pictures or videos to show the phenomenon of these faults, so that operators can recognize the faults quickly in actual work.

4.2 Fault Handling Methods

Second, the training should teach operators the correct methods to handle these faults. It should be emphasized that before handling any fault, operators must stop the equipment and cut off the power to ensure safety.

For example, when handling cardboard jamming:

Stop the equipment and cut off the power.

Open the protective cover of the jamming area (such as the folding unit).

Gently take out the jammed cardboard (do not pull it hard to avoid damaging the equipment or the cardboard).

Check the cause of the jamming: if it is due to uneven feeding, reduce the height of the stacked cardboard; if it is due to a worn conveyor belt, report to the maintenance personnel to replace the conveyor belt; if it is due to incorrect adjustment of the folding plate, adjust the position of the folding plate according to the instructions.

For uneven gluing:

Stop the equipment and check the glue tank: if the glue is insufficient, add fresh glue; if the glue is expired, replace it with new glue.

Check the glue pipeline: if it is blocked, use a cleaning agent to unblock it.

Check the glue roller: if it is worn, report to the maintenance personnel to replace it; if the glue amount is incorrect, adjust the glue amount through the control panel.

In addition, the training should also teach operators to distinguish between faults that can be handled by themselves and faults that need to be handled by maintenance personnel. For example, if the equipment has abnormal noise due to damaged gears, operators cannot handle it by themselves and need to report to the maintenance personnel in time, and do not disassemble the equipment without permission.

4.3 Fault Recording and Reporting

Finally, the training should emphasize the importance of fault recording and reporting. Operators need to record the time, type, cause, and handling method of each fault in the “Equipment Fault Record Book”, so that the workshop management can analyze the fault trend and take preventive measures (such as regular maintenance of the parts that are prone to failure). At the same time, if a fault cannot be handled within 30 minutes, operators need to report to the supervisor immediately to avoid affecting the production schedule.

5. Daily Maintenance Training: Extend the Service Life of the Equipment

Daily maintenance is essential to extend the service life of the folder gluer machine, reduce the frequency of faults, and ensure the stability of production. Operators are the first persons responsible for the daily maintenance of the equipment, so they need to master the basic maintenance skills.

The training content of daily maintenance includes:

Lubrication: The rotating parts of the folder gluer machine (such as bearings, gears, and conveyor belt rollers) need to be lubricated regularly to reduce friction and wear. Operators need to know which parts need to be lubricated, what type of lubricating oil to use (such as No. 30 machine oil), and how often to lubricate (usually once a week). During the training, instructors will demonstrate how to add lubricating oil to the bearings and gears, and remind operators not to add too much lubricating oil (to avoid oil stains on the cardboard).

Tightening: The vibration of the equipment during operation may cause the screws and nuts of the parts to loosen. Operators need to check the tightness of these fasteners every day before starting the equipment, and tighten them if they are loose. For example, the screws of the folding plate and the glue roller are prone to loosening, which may lead to incorrect folding angle or uneven gluing if not tightened in time.

Cleaning: As mentioned in the post-operation treatment, operators need to clean the equipment every day after use, including the glue roller, glue pipeline, conveyor belt, and folding unit. In addition, operators need to clean the dust in the electrical cabinet once a month (with the power cut off) to avoid short circuit caused by dust accumulation.

Inspection: Operators need to conduct a comprehensive inspection of the equipment once a week, including checking the wear of the parts (such as the conveyor belt and glue roller), the tightness of the belt, and the normal operation of the electrical components (such as the emergency stop button and control panel). If any problems are found, they need to report to the maintenance personnel in time for repair or replacement.

6. Quality Control and Production Management Training: Ensure the Stability of Production Quality

In addition to operating the equipment, operators also need to participate in quality control and production management to ensure that the quality of the cartons meets the requirements and the production tasks are completed on time.

6.1 Quality Control Standards

The training should let operators master the quality control standards of the cartons, such as the bonding strength (tested by a tension tester, the bonding strength should not be less than 5N), the folding accuracy (the error of the carton size should be within ±1mm), and the surface quality (no glue stains, scratches, or wrinkles). Operators need to know how to use simple testing tools, such as a ruler to measure the size of the carton and a hand-held tension tester to test the bonding strength. During production, operators need to conduct random inspections of the finished cartons according to the standards, and isolate the unqualified products to avoid mixing them into the qualified products.

6.2 Production Schedule Management

Operators need to understand the production schedule of the workshop and adjust the operation of the equipment according to the schedule. For example, if the production task is tight, operators can appropriately increase the feeding speed of the equipment (within the allowable range of the equipment) to improve production efficiency; if the next process needs the cartons urgently, operators need to prioritize the production of that batch of cartons. In addition, operators need to record the production data every hour, such as the number of finished cartons, the number of unqualified products, and the downtime, and report these data to the supervisor. This helps the workshop management to grasp the production progress in real time and adjust the production plan if necessary.

Conclusion

The training for folder gluer machine operators is a systematic project that covers safety operation, equipment knowledge, practical skills, fault handling, daily maintenance, and quality control. Only through comprehensive and in-depth training can operators master the skills of operating the folder gluer machine safely and efficiently, reduce the occurrence of faults and safety accidents, and ensure the stability of production quality and efficiency. For enterprises, investing in operator training is not only a guarantee for the normal operation of the equipment, but also an important measure to improve the competitiveness of the enterprise in the packaging industry. Therefore, enterprises should formulate a scientific training plan, hire professional instructors
